IMPROVEMENT IN LAM P-BU RNERS.

Specification forming part of Letters Patent N 0. 36,367, datedSeptember 2, 1862.

To all whom it may concern):

Be it known that we, F. J. REBBEOK and ED- WARD M. DAVIES, of Pittsburg,in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in Lamp-Burners, such as are used with glasschimneys for burning coal-oil and similar bydrocarbons; and we do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 is a vertical centralsection of our invention, taken in the line a: 00, Fig. 2. Fig. 2 is aplan or top view of the same with the chimney and cone or deflectorremoved; Fig. 3, an external view of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to obtain a lamp-burner for burningcoal-oil and similar fluid hydrocarbons, which will admit of the wickbeing lighted, and also trimmed when necessary without removing theglass draftchimney or detaching any of the parts of the burner.

To this end the invention consists in exposing the upper part of thewick-tube either by moving the same vertically or moving a case whichencompasses it, one or more openings being made in the latter and theformer provided with a perforated cylinder,which,when the burner is inuse, serves to close the openings in the external case which inclosesthe wick-tube.

To enable those skilled in the art to fully understand and construct ourinvention, we will proceed to describe it.

A represents the body or fountain of the lamp, and B a metal cap, whichis screwed into the upper part of the latter, said cap having a flat oroblong rectangular socket, 0, secured centrally within it, and throughwhich socket the wick-tube D passes into the fountain A. The wick-tubeis allowed to work freely up and down through the socket O, and it isthus operated by means of a pinion, E, gearing into a rack, F, attachedto the wicktube, as shown clearly in Fig. 1, the pinion E being placedon a shaft, G, provided with a thumb-wheel, H, at one end.

The wick-tube D is provided near its upper part with a perforatedcylinder, I, in which a shaft, J, is fitted, having upon it two serratedwheels, at a, which pass through slots b b in the wick-tube and areincontact with the wick a. By turning these wheels the wick may be raisedand lowered, as usual.

K is a case or hollow cylinder which encompasses the wick-tube D, and issecured at its lower end to the cap B. To the upper end of this case Kthere is attached permanently a flange, L, in which the cone ordeflector M is fitted, and also the base of the glass chimney N, asshown in Fig. 1. The upper part of the case K,'just below the flange Land at opposite sides, is provided with two openings,

d d, as shown in Fig. 3, and the flange L is perforated, as shown at e.The upper surface or ,top of the cylinder I is also perforated, as shownatf, and is open at its bottom. (See Fig. 1.)

When the burner is in use, the wick-tube D is raised, so that theperforated cylinder I will close the openings d d of the case K, airbeing admitted to the flame through the perforations of said cylinderand also through the perforations in the flange L, as indicated by thearrows in Fig. 1.

When the wick-tube D is thus raised,its upper end bears the samerelative position with the cone or deflector M as that of an ordinaryburner.

In order to light or trim the wick, all that is required is simply tomove down the wicktube D and its cylinder I, which is doneby turning theshaft G of the pinion E until the upper end of the wick-tube arrivesopposite the openings d d, the cylinder I being then below saidopenings,and the upper end of the wick-tube exposed, so as to render thewick accessible to either a match or shears. When the wick is lighted,the wick-tube is raised or moved upward to its former position throughthe medium of the rack and pinion F E. Thus by this simple arrangementthe wick may be trimmed and lighted without removing the chimney ordetaching any of the parts of the burner; and its principal advantageover other devices of the kind consists in the obtaining of betterdraft, which is due to the increased length of the burner obtained bythe arrangement, as described, of the wick-tube and case, and, further,the facility with which the wick may be trimmed, the shears beingallowed to pass entirely through the case. This result cannot beattained by a stationary wicktube within the deflector, and in thisrespect our invention difiers from all others of the kind that havepassed under our observation.

It will be seen from the above description that the same end may beattained by having the wick-tube stalionary and the case K arranged toslide up and down; but the same parts would be necessarily used in bothcases and the character of the invention not be in the least changed.

We would remark that in order to prevent the casual falling of thewick-tube D the cylinder I may be provided with a spring-catch, soarranged as to pass through one of the perforations at the side ofcylinder I and project over the lower edge of one of .the openings d.(See Fig. 1.) v

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent,'is

The wick-tube D, provided with a hollow perforated cylinder, I, andencompassed by a case, K, having one or moreopcnings, d, made in it, andprovided with a flange, L, to receive the case or deflector M anddraft-chimney N, when said parts are arranged to admit of the verticalsliding of either the wick-tube or case, so as to expose the upper endof the wicktube when necessary for the purpose of lighting or trimmingthe wick, and also to inclose fully the wick-tube when the burner is inuse, substantially as herein set forth.
